The PRSalpha ATC is the affordable CNC solution that delivers high performance, high volume, speed, and reliable power. Just like our PRSalpha tool, it provides full-production performance in the digital fabrication of wood, plastic, aluminum, and other materials, but the PRSalpha ATC has the added capability of an Automatic Tool Changer. An ATC reduces production time by automatically changing cutters between tool paths, thus eliminating the need for the CNC operator to change and zero tools individually. This allows the PRSalpha ATC to do the full job, even when different tooling is required to make different types of cuts – like cabinets and furniture – or where different bits are needed for roughing and finishing passes – like signs and complex 3D carvings. A machine equipped with an ATC can perform operations normally done on other pieces of equipment, eliminating the need for additional machines in the shop.

Available in traditional shop-size and larger, PRSalpha ATC tools are available with 8” or 14” Z travel. In addition to our standard size tools – 96 x 48, 96 x 60, 120 x 60, 144 x 60 – we can build your tool to any dimension up to 10’ by 30’ and with plunge depths up to 24 inches. Other customizable components are available.

Give us a call and speak to a member of our sales team to discuss your production needs. We’ll help you find the right configuration to get the job done.

While there are endless possibilities of what you can do with the ShopBot PRSalpha, here are a few examples of areas where people are putting their CNC tool to use:

Cabinet Making

With CNC, cabinetmakers can drill shelf pin holes, cut rabbets and dados, and profile-cut a completed panel. The operator only needs to handle the full sheet once to load the machine, and then remove the perfectly cut parts when complete.

Theaters and Museums

Realize your team’s aesthetic vision and go quickly from hand drawing to CAD design to full-size scenery panels. Complexity is easily incorporated when using CNC, so you can execute all kinds of ideas—including creating components in 3D.

Sign Making

Sign makers are using CNC for 3D carving, V-bit carving, profile contouring, fluting, and engraving. It also provides them with the opportunity to cut their own channel letter components, frames, posts, and borders in-house.

Furniture

High-volume furniture and millwork companies, as well as novice and master craftsmen, are embracing CNC technology. Craftsmen are quickly realizing that the CNC process doesn’t jeopardize their pieces' authenticity; it only adds to quality and uniqueness of the finished product.

Accessories

ShopBot offers accessories and add-ons for your tool. Here are a few of our most popular items.

Rotary Indexer

Rotary Indexer

Like a lathe, a rotary indexer provides a 4th rotary axis for turning a part, but it also provides precise “indexed” control over rotation.

Learn more about CNC Indexers
Hose Cradle Kit

Hose Cradle Kit

We have designed a system that not only keeps the dust hose free from the cutting area, but the hose is also contained to keep it more streamlined.

Learn more about the Hose Cradle Kit
Vacuum Hold Down

Vacuum Hold Down

Vacuum is one of the most effective methods to hold down parts for CNC cutting and machining. We offer options for universal hold down systems.

Dust Collection

Dust Collection

Proper dust collection not only ensures the cleanliness of your shop, it also protects your lungs from the various materials released into the air of your work space.
